Stephen Miller outlines the coming migration policy:

Seal the border, deport all the illegals. ... [Then] add safe thirds, remain in Mexico. Finish the wall. Robust prosecutions of illegal aliens, interior repatriation flights into Mexico, not back to the north of Mexico. Re-implement Title 42, 212 Fs, Travel Ban . . . bring those back and add new ones on top of that.

Establish large scale staging grounds for removal flights: grab migrants, move them to the staging grounds, federal law enforcement ships them off on planes back home.

Deputize the National Guard to carry out immigration enforcement, deploy the military to the southern border, not just with a mission to observe but with an impedance and denial mission.

In other words, you reassert the fundamental constitutional principle that you don't have a right to enter into our sovereign territory to even request the asylum claim. The military has the right to establish a fortress position on the border, and to say no one can cross here at all.
